DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1 and Figure 2 As shown, the automatic tea-dumping tea box of the tea plucking machine includes a bracket 1, a frame 2, a box body 3, a cover plate 4 and a flip structure. The bottom front end of the box body 3 is rotatably set on the frame 2, and the frame 2 can be raised and lowered on the bracket 1. The front end of the box body 3 is provided with an outlet for pouring out tea leaves, and the cover plate 4 is rotatably hung at the outlet of the box body 3. The flip structure is used to drive the lifting and dumping of the box body 3 and to drive the opening and closing of the cover plate 4. The box body 3 has an inner cavity, and two groups of inclined plates 22 are symmetrically arranged in the box body 3. The inclined plate inner cavity is divided into two partition chambers 23. The bottom front side of the partition chamber is fixedly inclined with a guide plate 24. The guide plate is located on the outlet side of the box body 3. The two groups of inclined plates and the bottom surface of the box body 3 form a material cavity 25 for storing substances.

[0021] This automatic tea-tip tea box needs to be used in conjunction with a fully automatic tea plucking machine. After the fully automatic tea plucking machine cuts the tea leaves, it sucks the tea leaves into the tea box through the suction principle, which plays the role of collecting tea leaves. When the tea leaves are collected, the box body 3 is first lifted by the side-turning structure, and then the box body 3 is driven to gradually flip forward relative to the frame 2. At the same time, the cover plate 4 is gradually opened under the action of the side-turning structure, so that the tea leaves in the box body 3 are gradually poured out. After the tea leaves are poured out, the box body 3 can be reset.

[0022] Because of the existence of two partition chambers, the tea leaves are poured out evenly from both sides, so the pouring range and amplitude can be better controlled. Unlike when all the tea leaves are piled in the same inner cavity and poured out, there will not always be a large amount of tea leaves piled in the center due to gravity.

[0023] Materials can be stored in the material cavity, mainly used to store bags. When the tea needs to be poured out, the bag is directly taken out from the material cavity, and then after the bag is opened, the tea in the box 3 can be poured into the bag to complete the collection.

[0024] A support rod and two sets of support legs 26 are fixedly provided in the box body 3. The support rod includes a vertical rod and a cross rod 27 fixedly provided on the vertical rod. The support rod is located in the center of the box body 3. The two sets of support legs are symmetrically arranged relative to the support rod. The two sets of inclined plates are formed by bending the same plate. The bottoms of the two sets of inclined plates are respectively fixed on the support legs, and the bent part of the plate is placed on the cross rod.

[0025] The reason for making it in the form of an inclined plate is to make the partition cavity form a cavity shape that is larger at the top and smaller at the bottom. This way, the process of pouring out the tea leaves is most efficient because the amount of tea leaves at the top is greater and needs to be poured out first.

[0026] A skylight 28 is provided above the casing 3, and the skylight is detachably provided with a skylight. The existence of the skylight can provide sunlight exposure for tea leaves in the casing 3 on the one hand, and people can also operate or observe the situation of the internal tea leaves from this place on the other hand.

[0027] The support 1 is provided with a handle 29 for facilitating human climbing. The user can go up to the position of the skylight along the handle, and it will be more convenient for the user to drive the tea plucking machine after the lifting.

[0028] like Figures 3 to 6 As shown, the rollover structure includes a lifting assembly for changing the height position of the frame relative to the bracket, a tipping assembly for changing the tilt angle of the box relative to the frame, and an opening assembly for changing the covering degree of the cover relative to the outlet.

[0029] When the box is full of tea leaves and needs to be poured out, the box must first be raised to a sufficient height through the lifting assembly so that a collection bag and other objects can be placed under the box to complete the collection. Then, in order to pour out the tea leaves, a tipping assembly is needed to realize the side-over and tipping function of the box. At the same time, the cover plate cannot be always at the exit of the box, otherwise the tea leaves cannot be poured out. Then, the opening and closing angle of the cover plate is changed through the opening assembly to enable the tea leaves to be poured out.

[0030] The tilting assembly includes a tilting fixed block fixed on the frame and a tilting motion block fixed on the box body. A driving hydraulic cylinder and a first rocker are coaxially rotated on the tilting fixed block. A second rocker is rotatably provided on the tilting motion block. The ends of the first rocker and the second rocker are rotatably connected, and the end of the piston rod of the driving hydraulic cylinder is rotatably connected to the middle of the second rocker.

[0031] The function of the first rocker arm and the second rocker arm is to make the positional relationship of the entire tipping assembly on the frame and the box body uniquely fixed. From a mechanical point of view, it is limited to one degree of freedom or a kinematic pair, and then the second rocker arm is subjected to force by the top pressure of the driving hydraulic cylinder to change the positional relationship. However, because the entire tipping assembly itself has only one degree of freedom, the piston rod of the driving hydraulic cylinder is extended or retracted to any position point. The state of the box body relative to the frame is unique, which has good reliability and can change the tilt position of the box body.

[0032] In an ideal state, the cover can be hung freely relative to the box body, because when the box body is tilted, the cover will automatically hang down to expose the outlet. When the box body is upright, the cover will be perpendicular to the ground due to gravity, so the box body can also cover the outlet. However, this is all under ideal conditions, because the weight of the tea leaves in the box will press against the cover plate from the side, causing it to open. Moreover, due to the potholes on the ground, if the cover plate is not limited and is just hung during the stepping process of the tea picking machine, it will shake and open and close, causing the tea leaves to fall out of the outlet. Therefore, a cover opening component is still needed to control the opening and closing of the cover plate.

[0033] The opening plate assembly includes a first fixed body fixed on the frame, a second fixed body fixed on the cover plate, an opening plate chain, and an opening plate reversing wheel group. The two ends of the opening plate chain are respectively fixed on the first fixed body and the second fixed body. The opening plate reversing wheel group is arranged on the frame and the box body to ensure that the opening plate chain is always in a taut state.

[0034] Because the cover plate needs to change its angle relative to the box body, the two ends of the opening chain cannot be fixed on the box body and the cover plate, because the opening chain needs to be in a taut state to play its traction function, so if the opening chain is fixed on the box body and the cover plate and is taut, then the opening chain will not be able to open and close.

[0035] To this end, this design fixes the two ends of the open-plate chain on the cover and the frame. Because the box needs to operate relative to the frame, and the cover needs to operate relative to the box, the cover and the frame are movable relative to the box. Then the box can act as an intermediate medium. By reasonably designing the open-plate reversing wheel group and changing the path direction of the chain, the chain can pull the cover to change its position while being taut.

[0036] The open plate reversing wheel group includes a first reversing sprocket rotatably arranged on the frame, a second reversing sprocket rotatably arranged on the box body, a third reversing sprocket rotatably arranged on the frame, and a fourth reversing sprocket rotatably arranged on the box body. The open plate chain passes through and is hung on the first reversing sprocket, the second reversing sprocket, the third reversing sprocket, and the fourth reversing sprocket in sequence.

[0037] The function of the first reversing sprocket, the second reversing sprocket, the third reversing sprocket and the fourth reversing sprocket is to keep the opening chain in a tensioned state. Then, through the length limitation of the opening chain itself, after the box body is tilted relative to the frame, the cover plate will also be flipped open due to its own gravity. However, due to the tensioning and limiting effect of the opening chain, the degree of opening of the cover plate is fixed. This is a pop-up process. The main purpose of this design is still for the closing function of the cover plate. When the tilting assembly straightens the box body relative to the frame, the opening chain will pull the cover plate tightly, so that the cover plate will not flip open freely, thereby playing a reliable blocking function.

[0038] The opening assembly also includes a telescopic rod, the two ends of which are rotatably mounted on the box body and the cover. The telescopic rod provides a reliable function, ensuring that the cover is stable and slow in the process of opening or closing.

[0039] The lifting assembly includes a lifting drive motor fixedly arranged above the bracket, a fixed sliding sprocket fixedly sleeved on the end of the output shaft of the lifting drive motor, a lifting fixed body fixedly arranged below the bracket, a lifting chain with one end fixed on the lifting fixed body and hung on the fixed sliding sprocket, and the other end of the lifting chain is fixedly connected to the frame. After the lifting drive motor is operated, the fixed sliding sprocket rotates and pulls the lifting chain through the fixed sliding sprocket to achieve the change of the height position of the frame relative to the bracket.

[0040] During the lifting process, the lifting drive motor drives the entire frame to lift, and only after lifting can the box be poured out from the top to the bottom of the tea. Because the box is originally in a bottom-up environment, in order to pour out the tea inside the box and collect the tea immediately from the bottom, the box needs to have a lifting function.

[0041] from Figures 3 to 6 The side-turning structure embodies the entire process of pouring out tea leaves in one process. First, the box body needs to be lifted to a sufficiently high height along with the frame, and then a packaging bag for collecting the poured tea leaves is placed at the tail of the tea plucker. Then, the tea leaves automatically complete the opening function of the cover by flipping the box body relative to the frame, and then the tea leaves can fall out of the outlet into the packaging bag.

[0042] It should be understood that in the claims and description of the present invention, all "including..." should be understood as open-ended, that is, its meaning is equivalent to "at least containing...", and should not be understood as closed-ended, that is, its meaning should not be understood as "only including...".

[0043] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
